Answer:
Q.1
Given-
Volume of solution-1 L
Molarity of solution -6M
to find gms of AgNO3-?
Molarity = number of moles of solute/volume of solution in litre
number of moles of solute = 6×1= 6moles
one moles of AgNO3 weighs 169.87 g
so mass of 6 moles of AgNO3 = 169.87×6=1019.22
so you need 1019.22 g of AgNO3 to make 1.0 L of a 6.0 M solution
Answer:
The control subsystem of a vehicle can have several parts. Two examples are the braking and steering wheel. If the subsystem were to malfunction, driving could potentially be dangerous due to the fact that the car could go out of control and make an impact on another car. For example, if the brakes aren’t working you cannot stop the vehicle in time and if the steering wheels went you can’t move the vehicle.
The helium would expand into the air of the room. Depending on how big the room is, and the amount of helium in the jar, it could cause damage to health. The only way this would happen is if the room was small and the jar was big.
I hope this helps!
Answer:
![Kc=[Cl2]2/[HCl]4[O2]](https://tex.z-dn.net/?f=Kc%3D%5BCl2%5D2%2F%5BHCl%5D4%5BO2%5D)
Explanation:
Hello,
In this case, the law of mass action, allows us to study the mathematical expression regarding an equilibrium chemical reaction allowing us to see a relationship between the equilibrium constant and the concentration of both the products and reactants at equilibrium for either gaseous or aqueous substances only. Such relationship is assembled as the quotient between the concentration of products at equilibrium over the concentration of reactants at equilibrium equaling the equilibrium constant. Thus, for the given chemical reaction, such expression will have the concentration of chlorine at the numerator and both the concentrations of hydrogen chloride and oxygen at the denominator since water is liquid so it is not included in the shown below equation:
![Kc=\frac{[Cl]^2}{[HCl]^4[O_2]}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5BCl%5D%5E2%7D%7B%5BHCl%5D%5E4%5BO_2%5D%7D)
Therefore the answer is: Kc=[Cl2]2/[HCl]4[O2].

Only CH3OH contains convalent bonds. Others are metal. But CH3OH is methanol.
